For those who don't know, TI's Hybrid Digital technology is a way to amplify audio with digital efficiency while retaining analog compatibility. Delta Sigma converts the analog signal into a quasi-digital bitstream that can be very efficiently amplified.
At normal listening levels, power usage is only 25mA at 12v, or just 300mW! In contrast, analog amplifiers use as much as 90W.
In addition, the iHybrid has DC power input for alternative energy compatibility, a line in that can be used at the same time as the iPod, and remote control with support for basic iPod control.
I named it after my best friend, who is an environmentalist.
